Weich-elastische Polymerschaumstoffe - Polyurethanschaumstoffe für Polsterzwecke mit Ausnahme von Teppichunterlagen - Anforderungen (ISO 5999:1982)
Diese Internationale Norm legt Anforderungen an elastische tragende Polyurethanschaumstoffe vom Polyether-Typ fest.
Sie gilt für weich-elastische Polyurethanschaumstoffe, die als Schaumblock, in Platten und Streifenform, als Formkörper sowie als rekonstituiertes Material für allgemein tragende Anwendungen, mit Ausnahme von Teppichrückseiten und -unterlagen hergestellt werden. Die Norm bezieht sich folglich in erster Linie auf die Qualität von Polyurethanschaumstoffen zur Anwendung für Polsterzwecke.
Der Schaumstoff wird entsprechend dem Verhalten während einer Ermüdungsprüfung klassifiziert, wobei die Eindrückhärte als eine zweite Möglichkeit zur Einstufung des Materials dient.
Diese Internationale Norm gilt weder für Hinterschäumungen, noch für Schaumstoffe zur Verwendung in heißgeschweißten Systemen, außer für tragende Anwendungen.
Empfohlene Anwendungen für den Bereich weich-elastischer Polyurethanschaumstoffe entsprechend dieser Internationalen Norm werden in Anhang B aufgeführt.

Foreword
ISO ithe International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing Inter-
national Standards is carried out through ISO technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 5999 was developed by Technical Committee ISO/TC 45,
Rubber and rubber products, and was circulated to the member bodies in
September 1979.
